Abstract: Modeling of human face is always a challenging task in computer graphics.How to quickly and efficiently restore a realistic three-dimensional human face，is one of the difficulties.This paper presents a fast 3D facial modeling method，the method divides face model into a number of relatively independent functions of movement，then in all functional areas uses the weighted free deformation DFFD for face model deformation.Since the introduction of functional areas，the number of control points greatly decreased，greatly reducing the amount of computation，can well meet the real-time and more authenticity.
